It’s very easy to add your own logo. No need to install plugins. Just add some line of code to your theme’s funtion.php file and you can feel the different. I think, this is very helpful for WordPress Multisite Users. How it’s possible?. Please follow these steps.

Step 1: Creating Logo Image

If you are using a new version of WordPress(3.2x) blog, create an image with 16×16 pixel size or if you are using an old version create an image with 30×30 pixel size. Here I set “dash_board_logo.png” as it’s file name. You can create the logo image in any format (.gif, .png, .jpg) as you like. Save it into your theme’s image folder like “/your_theme_folder/images/“.

Step 2: Setting Image

16×16 pixel size is very small. If you want to show big image instead of 16×16 pixel image in your new WordPress version dashboard, set it’s width and height as you like. Here I like to set 30×30 pixel size, then the code become like this

Step 3: Adding image to Dashboard

Open your theme’s function.php file. Create a function dashboard_logo(). Copy and paste the CSS script, that we written above. Now it’s time for add the CSS script to your admin page, by using WordPress’s add_action() funtion.

Here’s the final script to replace your WordPress dashboard logo with your own logo.
